SPRAY HEAD.

. Application filed October 11, 1922. Serial No. 593,747. 7

To all whom it may concern Be it known that I, ARTHUR KmToN,

a citizen of Great Britain, and a resident of chines of the spray typeand has for its object to provide apparatus of the character designatedwhich shall be highly effectivein the production of a washing spray, andwhich may be readily cleansed as is desirable in apparatus of thischaracter.

In the accompanying drawing, Fig. 1 is a side view, partially insectionand partially in elevation, of a spray l1ead e1nbodying a preferred formof my invention; Fig. 2 isa top plan view of the apparatus shown in Fig.1; and Fig. 3 is an end view of the apparatus shown in Fig. 1, partiallyin section and partially in elevation. I

In a copending application of Henry F. Schmidt, Serial No. 593,724:filed October 11, 1922, thereis described and claimed a dish washingmachine embodying means for maintaining two .or more horizontallydisposed'tiers of dishes, vertically displaced from each other and withmeans for providing a whirling spray therebetween.

The present invention relates to a specific form of spray head which ishighly efi'ecspect thereto.

tive when used in such amachine.

Referring to thedrawing, I show at 5 an upstanding fluid supply pipeterminated in an open upper end. 5

A T-shapedmember 6 isprovided with a hollow stem 7 adapted to telescopeover the endof the pipe 5 and also, carries a weight member 8,symmetrically disposed with re- The head portion of the T- sha pedmember 6 is inthe form of'a' substantially semicircular trough, openingupward, as clearly shown in Fi 3 and the two ends of this;

trough-shape portion are closed by substantially quarter-sphericalportions 9 and 10, so terminating that the plan' View of the upper faceof thetrough is as shown in Fig. 2, being in form of a rectangle withcircular ends. One side of one end of the head member is perforated,asshown at 11, and the other side of the other end is similarlypervforated (not shown), The trough-shaped head is closed bya covermember 12 in sliding engagement therewith, this cover member being ofthe shape shown in Fig. 2 and having lateral depending flanges 13 and 14for engagement with suitable flanges on the straight edges of thetrough-shaped memher. The cover member 12 embodies semicircularextensions at the end thereof for the complete closure of thetrough-shaped memher. The cover member 12 is suitably perforated asshown at15 for the emission of upwardly directed sprays.

A flow directing member 16 is mounted within the trough-shaped top ofthe memher 6 and is of such contour that a circular stream of fluidrising from the pipe 5 is split into two semi-circular streams of fluid,

directedinto the respective ends of the head of the member 6. The member16 is suitably supported fromthe side walls of the member 6 and ismerely in contacting engagement with the cover member 12.

Having thus described the structure of apparatus embodying my invention,the operation thereof is as follows: Upon the supply of fluid throughthe tube 5 to the head 6, downwardly directed sprays are produced at theperforations 1111 and upwardly directed sprays are produced at theperforations 15-15. The fact that a preponderance of the sprays on oneend of the head member are on one side thereof, and a preponderance ofthe perforations of the other end of the head are on the opposite sidethereof, causes an unbalanced reaction tending to rotate the entiremember 6 about the axis of the member 5, thus providing the desiredwhirling spray action.

. While I have shown all of the perforations in one end of the headmember as located on one side thereof, it will be obvious that a certainnumber of perforations may be placed on the other side thereof, the mainrequisite being that there be (i-preponderance on one side so as tocause the unbalanced rotating action.

The actionof the member 16' is to cause a smooth, uniform, divergingdirection of the incoming stream to the respective pen 'forations andthe weight 8 prevents the pressure of the'incoming fluid from blow.lbodily from the pipe 5 and removed from the machine, andthe covermember 12 may then he slid therefrom, exposing the entire interior ofthe spray head for such cleansing as may be necessary. lVhile I haveshown but two radiating arms, it is obvious that I may employ a greaternumber of radiating arms with suitably adapted removable coverstherefor.

ll' hile I have shown my invention in but one form, it will be obviousto those skilled in the art that it'is nctso limited, but is susceptibleof various other changesand modifications, without departing from "thespirit thereof, and I desire, therefore, that.

only such limitations shall be placedthereupon as are imposedlby theprior-art or as are specifically set forth in the appended claims.

What I claim is; H

1. A spray head comprising a substantially horir'aontally disposed,hollow,
